A intermittent forward inoElements are'. imparted to the rotary die 5 from the upper diecarrying cross head A2 0 through the inedium of a rod 25, (shown, hy dotted lines, inig. if) said rod acting on a lever 2G, which is connected hy a link 27 to one arm of a lever 28 mounted so as to rock on the shaft of the die 5, the other arm of said lever carrying a pawl 29 which engages the teeth of a ratchet Wheel 3() on said die. Another link .3l serves to connect the lever 26 to an arm 32 on the rock shaft i6 so as to impart Y the desired rocking movement to the letter.

By Jche use of the rotary die 5 the freeing vof the'projecting ends of the Wings 3 from the sockets 6 1n said die'is automatically eifected as the die rotates, no raising of the film from the face 'of the die being necessary for this purpose, and by properly regulating the approach of the clenching die to-the die 9 the gage or thickness of the reinforced vportion of the strip canalvvays be accurately determined, or, if desired, this may be effected by means of a pair ol", gage rollers 33 and 3l between which the 'reinforced llni passesnfter it has left thedies 8 andi), f

ln the drawing l have only shown the ap' plication of the reinforcing strip' to oneedge `ofthe film, but it can, of course, be appliedy to both edges of the same, if desired, this involvin no more than mere duplication of rimessa 3 passing through the periorations in the iilrn and in therehi-orcing strip ll.a and hsvlng their tips clenched against 'the under face-'of said strip la. The use oi the reinforcing strip Vupon but one face oi' the has, 'hor/over, proven to he amply sutil@ "in 'practise and is preferred.

psratus for applying a rei i to a perforated iilni, the combina- ,tion of a'socketedrotatahle die serving asa support for the reinforcing strip and ilrn,
